selectDatCpp: Function for subsetting remotely sensed data from the user...

In paulhegedus/OFPE: On-Farm Precision Experiments (OFPE) Data Management and Analysis Tools

Function for subsetting remotely sensed data from the user selected source. This function takes a matrix with all the remotely sensed data and returns a matrix with the selected data. This function exists because data such as precipitation and vegetation indices are collected from multiple sources, and the user can select the source based on their data preferences.

Description

The user also must pass in the column index of the data passed in that corresponds to the primary and secondary source for each variable.

Usage

selectDatCpp(
  dat,
  rr,
  prec_cy_1,
  prec_cy_2,
  prec_py_1,
  prec_py_2,
  gdd_cy_1,
  gdd_cy_2,
  gdd_py_1,
  gdd_py_2,
  veg_cy_1,
  veg_cy_2,
  veg_py_1,
  veg_py_2,
  veg_2py_1,
  veg_2py_2
)

Arguments

dat	A matrix with all of the remotely sensed data to select from.
rr	The number of rows in dat and df (must be the same).
prec_cy_1	The column index of the preferred precipitation source for the current year.
prec_cy_2	The column index of the secondary precipitation source for the current year.
prec_py_1	The column index of the preferred precipitation source for the previous year.
prec_py_2	The column index of the secondary precipitation source for the previous year.
gdd_cy_1	The column index of the preferred growing degree day source for the current year.
gdd_cy_2	The column index of the secondary growing degree day source for the current year.
gdd_py_1	The column index of the preferred growing degree day source for the previous year.
gdd_py_2	The column index of the secondary growing degree day source for the previous year.
veg_cy_1	The column index of the preferred vegetation index source for the current year.
veg_cy_2	The column index of the secondary vegetation index source for the current year.
veg_py_1	The column index of the preferred vegetation index source for the previous year.
veg_py_2	The column index of the secondary vegetation index source for the previous year.
veg_2py_1	The column index of the preferred vegetation index source for two years prior.
veg_2py_2	The column index of the secondary vegetation index source for two years prior.

Value

df Returns a completed table with selected data.
